HEATING DEVICE FOR EXPLOSION MOTORS.

Application filed December 8, 1921. Serial No. 520,983.

To all whom it may concern:

Be it known that I, JEAN JULns PAUL Manon, citizen of the Republic of France, residing at 28 Rue Beaurepaire, Paris, France, have invented certain new and useful Improvements in Heating. Device for Explosion Motors, of which the following is a specification.

The starting of the explosion motor is largely facilitated especially during cold weather, if the gas for the motor is intro duced in a warm condition into the combus tion chamber. In order to effect the heat ing of this substance, hitherto employment has been made of either the cooling water or of the combustion gases.

I prefer to employ as such a separate heat source the heat generated by an electric current in a suitable resistance heater. Such a resistance can be arranged internally or externally of reservoirs, bodies or pipings or the like conducting the gasoline, the air or the carbureted mixture.

The resistance can be placed at any suitable point, for example internally or externally of the gas suction pipe in or upon the carbureter, as for example at the point of its air inlet with or without special ap paratus.

Referring to the drawings which form a part of this specification:

Fig. 1 showsa sectional view of a heating body,

Fig. 2 shows a part for such heater,

Fig. 3 is a section on lines M-.'N of Fig. 2,

Fig. 4 is a sectional view of another fitting part,

"ig. 5 shows a modified form of a heater in section, and

Fig. 6 is a. sectional view of another modified form of the heater.

The apparatus shown in Fig. 1 comprises a tubelike body a provided at its base with a cone having a. threaded part b. A resistance c is designed especially to develop the maximum of heat when a current is sent through it. The resistance is connected with any battery generally in use in auto vehicles, motorcycles, aeroplanes, agricultural and industrial motors, fixed motors, and in general, in any explosion motors. This resistance comprises a metal filament arranged in spires upon plates or the like of asbestos or mica. This metal filament is composed preferably of an alloy of the following composition: thirty per centof nickel, fifteen per cent of copper,- fifty-two percent of tin and three per cent of platin' However. the composition is variableaccordingto the voltage or amperage in use. A threaded cover 0 screwed upon the apparatus hasone or more holes 03 permitting of being shut olfat will and serving to admitthe air sucked in by the motor. A nut 6 permits theap paratus to be applied either upon the carbureter or upon the gas suction piping. A filter containing several metallic sheets It of a very fine structure is secured in tube a to avoid every communication. of the'gases with the resistance unit, as in the minerslamps, which thereby excludes every danger of 'fire or explosion.

The apparatus may be placed at any suitable point of the gas piping or off the carbureter, but in every case theapparatus is attached above the throttle valve'and'between the latter and the compression chamber.

In order to place the apparatus into service it will suflice to connect the resistance circuit by means of the terminals 9 in circuit with a. battery of the car or in the light-current, in this latter case the apparatus is fitted with ordinary resistances, to open the air admission (Z of the device and to heat a few seconds with the electric current. The cold air sucked in by the motor first enters the apparatus and is heated'by direct contact with the heating resistance a and has a high temperature in the gas suction pipe.

Once the motor is started the current is iijiiterrupted and the air admission is shut O H In the device shown in Figs. 2 and 3 a threaded aperture a is provided in the integral extension 8 of the flange member 1-, this aperture communicating with a channel I) for hot air. The channel 6 leads to a central aperture 0 guiding the gas flow.

Fig. 4 shows a supplementary connecting piece adjustable at will upon the flange at a (Fig. 2) by means of threads d. This connecting piece t is provided with a hole threaded at e for fixing therein the apparatus in the same way as in the aperture a of Fig. 2.

The utilization of this auxiliary flange and of the said connecting piece has the advantage that the heater can be arranged in any convenient direction, horizontally, vertically obliquely, to the right or to the left of the vaporizer, so that it will be possible to place the apparatus in the most practical T t will 'be clear from the foregoing that by means of such additional fitting pieces the apparatus may be placed not only upon the gas suction pipe between the throttle valve and the compression chamber, at any point, directly or indirectly but also upon the cylinders, by piercing a hole in a suitable point of the same, threading the same and fitting the heater by means of convenient tubing and the like.

It is possible also to replace the compression cocks bysuch heating apparatus, for which purpose I prefer to employ a valve nipple assupport for the heater.

*In Fig 5 such a valve nipple arranged. upon the heater is shown, h representing the nipple'provided with threads The valve 'ball'is shown at a If the nipple'wi th its heater is arranged to replace the compression cocks of the cyl inders, it will be clear that the valve ball will rest ordinarily upon its seats The latter is provided with slits for the passage of'air'. T

The action of the device is as follows: v

Thesuction of the motor causesthe cold surrounding air to pass first into the main apparatus and to be warmed, whereupon the heated air is sucked into the cylinders without being hampered by the ball, because the air can circulate through the slits in the seat. On the contrary in the moment of compression thesame-ball shutsofl' the bottom part of the tube of hot air above the ball, whereby loss of gas in compression; explosion and exhaust is avoided.

With the form shown in section in Fig. 6K is a double flanged body carrying the resistance 1, preferably of the composition described; protected by acover 'm with inward layers of mica and aminantus formingrinsulating bodies, n indicating the terminals'of the resistance Z.

The heater is arranged between the flange of the carbureter'and the suction tube or between the latter and the junction pipe of the cylinder. The apparatus when in action heats the wall to a high temperature. By the suction of the motor the carbureted mix ture passes necessaril into the interior of this device, which is a continuation of the suction tube. The mixture is warmed and consequently the carbureted mixture is heated.

I want to state expressly that I do not limit myself to the executional form shown herein and that important modifications are possible without departing from the principle of my invention.

Having now described the nature of my said invention, what 1' claim and desire tosecure by Letters Patent, is

1. An attachment for an internal combustion engine comprising a flange member having an integral extension, said extension having a threaded aperture therein; a threaded member threaded to said flange member at its aperture; a tubular member on saidthreaded'member; and a resistance coil in said tubular member," said flange member being adapted to be secured at any suitable place to the suction pipe or the carbureter of said internal combustion engine. I I

2. An attachment for an internal combustion engine comprising a flange member havingnn integral extension said extension having a threaded aperture therein; an electric heater; and means for adjustably securing said heater to said flange member by means of said aperture, said flange member belng adapted to be secured at any suitable place to the suction pipe or the carbureter of said internal combustion engine.

3. A heater supporting device'for attachment to an internal combustion engine, comprising a flange element having a central aperture, and an extension provided" with a threaded aperture, said extension having a channel therethrough communicating with said apertures. 7 i

In testimony whereof I aflixed-"my' sig nature.
